PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

-E: will describe the underlaying queries of the \ commands (cool for learning!)
-l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Auto reconnect to wifi when lost connection

Before you start, make sure ip command is available on your system. In modern Linux distributions, ip replaces older ifconfig command. If net-tools package (that includes ifconfig) is not installed and you prefer using it, you can install it via sudo apt-get install net-tools.

Create script file

Use touch /home/pi/wifi-reconnect.sh to create a shell script file, with the following content:

#!/bin/bash

	Script para ler arquivos XML de eventos eSocial e exportar os dados para um arquivo CSV.
	"""

	#
	# simpleBool.py
	#
	# Example of defining a boolean logic parser using
	# the operatorGrammar helper method in pyparsing.
	#
	# In this example, parse actions associated with each
	# operator expression will "compile" the expression
	# into BoolXXX class instances, which can then
	# later be evaluated for their boolean value.
